Who Issues Warrants in Tinley Park
In Illinois an arrest warrant is signed by a judge. For Tinley Park that means the Circuit Court of Cook County, which hears every civil, criminal, family, probate, traffic and juvenile case.
A bench warrant follows a missed court date in any of those courts. Whichever kind it is, the warrant is part of the file of the case it was issued in, and the Circuit Clerk keeps that file.
For Cook County, SearchSystems opened and checked the court records page for the county at cookcountyil.gov/service/court-records-and-archives (page title: Court Records and Archives), which answered when SearchSystems opened it on September 23, 2026.
Illinois has no single public index of every trial court case; each court's records are looked up through that court.

Not one of the Cook County pages SearchSystems verified (the sheriff's, the court's and the prosecutor's) is a list of open warrants, so a check means asking the court or the prosecutor about a case by name.
